Field of The Invention

This invention pertains to an improved, tamper evident container for storing and dispensing flowable products. Background of The Invention

Currently, granulated or powder products, such as infant formula, are packaged in containers. Consumers or users of such containers have often found that it is difficult to open the container and to locate and remove the scoop from the packaging upon the first use without experiencing spillage. Once the container lid is removed or opened, the granulated or powdered contents are often packed into parts of the interior of the lid or top of the container, which results in spillage as the contents fall away from the lid or top. While some of the falling powder may fall back into the interior of the container, much of it is wasted and contaminated as it spills onto the surrounding workspace.

Additionally, containers may not adequately seal the contents after the container has been opened for the first time, allowing the contents to become oxidized and/or contaminated. The design of such containers also may permit undesirable and inadvertent discharge of the contents from various poorly sealed areas of the container.

Certain infant formula container designs are known in the art. For example, U.S. Patent Appl. Publ. No. 2008/0173657 discloses a container and congruent scoop assembly with a removable lid for holding powdered material. There is a need for an improved infant formula container that is tamper evident, that allows a user to accurately measure infant formula to be dispensed, that enables a user to open and re-open the container without contaminating the infant formula, that allows a user access to the measuring scoop without contamination of the contents, that minimizes pressure differentials to the container without compromising the contents of the container and which minimizes spillage and contamination of the contents of the container. Summary of The Invention

The present invention provides a container comprising: a body having a bottom and a side wall defining a reservoir; a collar attached to the top end of the body; a removable seal to seal the top of the reservoir; and, a lid hingedly engaged with the collar. The underside of the lid provides a docking station for holding a measuring device, such as a scoop, suitable for measuring the contents of the container. The container may also have a leveling bar located at or near the top of the reservoir to allow the contents of the scoop to be leveled so that a consistent amount is dispensed by the scoop.

The lid closes tightly against the collar to seal the can and prevent spillage of the contents. In the closed position, the docking station is inside the can so that any measuring device docked therein will be secure from loss or contamination.

The container may also include a tamper evident band on a portion of the lid and/or collar to indicate if the container has been opened. It may also include a tamper strip on one side which will indicate the amount or condition of the contents. Brief Description of Drawings

In one embodiment, the present invention provides a container suitable to hold flowable contents, such as a powdered or granular infant formula, which includes a removable seal to seal in the contents held in the reservoir of the container, a collar attached to the top of the container, and a lid hingedly attached to the collar. When the lid is open the contents of the container can be dispensed from the reservoir; when closed, the lid tightly engages the collar to seal in the contents. The underside of the lid, which is inside the container when the lid is closed, contains a docking station and sufficient space so that a measuring device, such as a scoop, may be stored securely within the can to prevent loss or contamination thereof. Optionally, a leveling bar for leveling the contents removed by the scoop is located near the top of the reservoir.

According to an exemplary embodiment, Figure 1 shows a perspective view of the infant formula container 100 in an open position. Infant formula container 100 includes a reservoir 101 configured to hold contents to be dispensed; a collar 102 affixed to a top end of the reservoir 101 ; the collar further comprising a removable seal 103 that seals the contents held in the reservoir 101 ; a lid 104, hingedly engaged with the collar 102, providing an open position wherein the contents of the container can be dispensed from the reservoir 101 or providing a closed position wherein the lid 104 is resealed to the collar 102. The lid 104 provides space and a docking station 106 for holding and storing a scoop 107. The container further comprises a leveling bar 108 for leveling the contents removed by the scoop 107.

The reservoir 101 of the infant formula container 100 is designed to hold granulated infant powder, or the like. The body of the container 100 is constructed of a suitable metal or plastic material to be a unitary member of approximately uniform wall thickness.

In one embodiment, the body of the container 100 is constructed from a metal material, including but not limited to tin, metal plated tin, and aluminum. In a separate embodiment, the body of the container 100 is constructed from a suitable plastic material that is recyclable or non-recyclable. Suitable plastics for forming the container 100 include, but are not limited to, polystyrene, polystyrene-acrylonitile, acrylonitile- butadiene-styrene, styrene-maleic anhydride, polycarbonate, high density polyethylene, polyethylene copolymers, polypropylene, polypropylene copolymers, polyethylene terephthalate, polyvinylcyclohexane, and the like, and blends thereof. In one embodiment, the container 100 will have a semi-transparent to transparent tamper evident strip as part of the side wall to allow one to see into the reservoir 101 and thus to visually indicate to a potential user the quality and/or volume of the granulated infant formula in the reservoir. Typically, containers of the invention are constructed to accommodate infant powder weights of: 100 to 2000g; more typically 500 to 1000g; for example 900g.

In one embodiment, the container 100 has a cylindrical body, providing a circular cross-section, and the collar 102 is circular. In another embodiment, the body has a rectangular cross-section and the collar is likewise rectangular. In any case, the lid 104 is shaped to snugly mate with the collar 102. Those skilled in the art will readily understand that other shapes are also feasible in the practice of this invention; the invention is not limited to the shapes described herein.

Referring now to Figure 2, there is shown a perspective view of the infant formula container 100 with the lid 104 in an open position with the removable seal 103 in the collar 102 in a partially opened position.

In one embodiment, the lid 104 will have a tamper evident band that is wrapped around the lid 104 of the infant formula container 100. In one embodiment of the band, there is a noticeable red strip between perforated lines to indicate to a user where to tear the tamper evident band off, and a container opening icon located in four places on the tamper evident band communicating to the user the best way to open the infant formula container. The tamper evident band also adds a level of security preventing the closure from opening during transporting, handling, shipping, shelf stocking and consumer handling.

A removable seal 103 is attached to container 100 at the top of the reservoir 101 to vacuum seal the contents in the reservoir 101 . The removable seal 103 allows for vacuum packaging of the contents in the container 100 and acts as an anti-tamper inner liner. One skilled in the art of food packaging will be familiar with such releasably or removably attached packaging seals. Specifically, metal processing, adhesive or heat may be used to attach a seal formed of polyvinyl chloride, polystyrene, metal foil, plastic foil or other suitable material to form an airtight seal. Therefore, opening of the lid 100 will not disturb the seal 103 unless the seal 103 is cut or removed by the use.

Referring now to Figure 3, there is shown a side view of the container 100 having reservoir 101 , collar 102, and hingedly attached lid 104. In one embodiment, the lid and collar are constructed from a suitable plastic material that is recyclable or non- recyclable.

Suitable plastics for forming the lid and collar include, but are not limited to, various polymers such as polystyrene, polystyrene-acrylonitile, acrylonitile-butadiene-styrene, styrene-maleicanhydride, polycarbonate, high density polyethylene, polyethylene copolymers, polypropylene, polypropylene copolymers, polyethylene terephthalate, polyvinylcyclohexane, and the like, and blends thereof.

As shown in Fig. 3, the lid 104 is dome shaped and hingedly attached to the collar 102, in a skirt and a sleeve type arrangement that allows them to snap together. The lid 104 and the collar 102 are connected together by a butterfly hinge and are molded as one piece. When closing the lid 104, the the lid 104 swings into the collar 102 to form a sleeve type seal. The outer diameter of the lid 104 and the inner diameter of the collar 102 are designed to have minimum clearance for air passing and to minimize air oxidation of the contents. On top of the collar 102, there is a sealing rim (bead), which has an interference fit with the lid 104, so that when the lid is pushed down to pass the sealing bead and the skirt, air is forced out through the minimum space between lid 104 and the collar 102 and a tight seal is obtained.

In Figure 4, there is shown a perspective view of a scoop 107. The scoop 107 consists of a bifurcated handle attached to a scoop bowl. The scoop handle is bifurcated where it connects to the scoop bowl to allow the scoop 107 to efficiently collect infant powder and avoid powder build-up on the handle, so less powder spills on the preparation area.

In one embodiment, the scoop 107 is molded from a suitable plastic material, which may be blow molded, by extrusion or injection. Suitable plastics for forming the scoop include, but are not limited to, various polymers such as polystyrene, polystyrene- acrylonitile, acrylonitile-butadiene-styrene, styrene-maleic anhydride, polycarbonate, high density polyethylene, polyethylene copolymers, polypropylene, polypropylene copolymers, polyethylene terephthalate, polyvinylcyclohexane, and the like, and blends thereof. In one embodiment, the scoop has a small opening at the bottom of the bowl to allow air to exit while collecting infant powder so that the powder will pack better in the scoop.

Figure 5 shows a perspective view of the leveling bar 108. Many of the problems of the prior art are solved by the infant formula container of this invention, which provides previously unavailable features including improved sealing capabilities, new ways to minimize contamination of infant formula and control spillage of the contents, integrated dispensing scoops, and strengthened containers that can further protect against spillage and damage to product due to adverse pressure differentials between the sealed product container and the external environment.

The embodiments of the present invention are suitable for use in many applications that involve manufacture, distribution, storage, sale, and use of flowable substances such as powders, granular materials, or liquids.
